Process & Technology
There are three rolling mills in the cold mill. They are the heavy cold mill, light cold mill and the 3-stand tandem mill. They all perform the same task of rolling the hot band from the hot mill to the finished sheet thickness. The finished thickness is about the thickness of a sheet of paper. If the finished coil were rolled out flat, it ...

Aluminium Hot and Cold Rolling | SpringerLink
The rolling of thin aluminum foil is a very specific process and differs from conventional cold rolling. This rolling mode is reached at thicknesses below app. 70 μm. With decreasing strip thickness, the specific roll force increases, which leads to an increasing elastic work roll flattening in the contact zone.

The cold mill roll gap should start out being set to the same profile as the crown of the incoming hot mill product. Then, as the cold mill gap is adjusted to reduce the crown, the coil also will come out flat--if the hot mill got the relationship between crown and flatness right to begin with. If the cold mill rolls or hot mill coils have too ...
